Lindsay Lohan's Highs and Lows

Sources tell E! News that Walters went to the set of "Liz & Dick" during production, where Lindsay showed her some behind-the-scenes action and participated in some interviews.

So in a couple of weeks, this material, plus a new, no-holds-barred interview that Lindsay will do with Barbara, is expected to be combined into a primetime special that will air sometime prior to the premiere of the Lifetime movie (which airs Nov. 25).

LiLo agreed to the interview as she greatly admires Walters and knows that the interview will be done with respect, a source told E! News.
